My teacher assigned a few problems, and I'm having difficulty with one of them. The question is:(adsbygoogle = window.adsbygoogle || []).push({});

In order to accelerate a 2 kg car from rest to a speed of 16 m/s, 400 J of work are done by the motor of the car. The acceleration takes 10s. Calculate:

a) the distance moved by the the car (I got 80 m)

b) its acceleration (1.6 m/s2)

c) the force provided by the motor

d) the frictional force opposing the car's motion

e) the work done to overcome friction

f) the final kinetic energy of the car

I need help especially with c and d. Thanks.
